UNCOUPLING DEVICE FOR CAR-COUPLINGE.

Specification of Letters Patent.

Patented Apia 23th,

Application filed February 16, 1914. Serial No. 819,051.

resident of Columbus, in the county of Franklin and State of ()hio, have invented certain new and useful Improvements in Uncoupling- Devices for Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in uncoupling devices for car couplings,the ob ect of the lnvention being to provide simple and efiicient devices for the raising of the locking pin or block of a car coupling, which shall be so operable from the side of a car andso constructed and arranged that the hand-operated portion. must be lifted for actuating the pin. lifting member and thus obviate danger of accidental operation which might occur were that portion to which power is to be applied arranged to be depressed or moved downwardly for a ctuating the pin or block lifting member.

With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view illustrating an embodiment of my invention, and Fig. 2 is a view showing a modification of the same.

lrepresents the end sill of a car and 2 illustrates a portion of a car coupling provided with a locking block or '3 having a loop or eye l at one end. if,

A. plate 5, provided with a boss 6, is rigidly secured to the end sill 1, and to said boss, one end of a lever is pivotally attached. This lever is disposed approximately parallel with the end sill and its contracted free end portion 8 passes freely through the eye or loop l of the locking pin or block 3,the free extremity of the portion 8 of lever 7 being preferably, made hook-shaped as indicated at 9. At a point between the pivotal connection of the lever 7 with the end sill and'the coupling 2, one end of a hand lever 10 is pivotally supported by the end sill, a boss 11 being provided. on the end sill to. facilitate pivotal connection of said hand lever to the end sill. A clip or 'or clip loop 12 (inverted U-shaped in vertical sec tion) is secured at its lower end to the hand lever 10 and embraces the lever 7 at a point between the pivotal connections of the ewe lovers to the end sill. A. bolt 13 passestransversely through the loop or clip 12 in such position as to be disposed under the lever 7 so that said lever may rest and move thereon. The hand lever 10 is made of such length that its hand-engaging portion shall be within convenient reach of a traininan at the side of the car.

When it is desired to raise the locking pin or block, the trainman will raise the free or hand-engaging end of the lever 10, and this movement will be transmitted by the loop 12 and bolt 13 to the lever 7 to raise the latter on its pivotal support and thus cause the free end portion of said lever 7 to lift the locking pin. By so constructing the devices that the hand lever niust be raised to actuate the pin lifting lever, the train-- man would fall away from the car in. the event of breakage of some part of the inech= anism, and furthermore, there will be no danger ofv accidental operation of the uncoupling mechanism, as might occur with constructions inwvhich downward hand or foot pressure on the actuating lever will cause the locking pin to be raised.

In the form of the invention shown in Fig. 2, the loop or clip 12 is omitted and the hand lever 10 is bent to form a shoulder 14; disposed under and engaging the lower edge of the lever 7 at a point between the pivotal connections of the two levers to the end sill.

Other slight changes might be made in the details of construction of my invention without departing from the spirit thereof too coupling provided with a locking pin, of;

a pin-ra1sing lever pivoted at one end to the end sill, an operating lever pivoted to the end sill between the ends of said pinraising lever and extending laterally past the pivoted end of the latter, a clip secured -specifieation in the presence of two subscribing Witnesses.
